Interestingly, I found a similar ordering dependency exists for set()
and frozenset():

>>> set() | frozenset()
set()
>>> frozenset() | set()
frozenset()

So the status quo is less consistent than I previously thought.

Regardless, it isn't enough to merely point out that the status quo is
inconsistent. It's necessary to make a case for why the proposed
change is sufficiently better to be worth the cost of making the
change: http://www.boredomandlaziness.org/2011/02/status-quo-wins-stalemate.html

Consider the "it's not worth the hassle" stodgy core developer
response invoked ;)

Cheers,
Nick.
